Description

Push-pull type vibration sorting device Technical Field The utility model relates to the field of material sorting devices, in particular to a push-pull type vibration sorting device. Background The existing material screening device is mainly characterized in that a driving mechanism drives a vibration exciter, and the vibration exciter forces a screen disc to vibrate, so that materials in the screen disc are displaced due to vibration, and materials meeting the specification requirements can be separated through screen holes. However, when it is required to sort out metal objects such as nails, nuts, small iron pieces, etc. from construction waste or construction tailings by a screening device, flocs are often easily entangled due to the rough surface of these metal objects, and cannot be sorted out through mesh holes when a screen tray is vibrated. Meanwhile, the materials are continuously poured into the sieve tray through the conveying belt, and the materials with larger area are contained, so that small metal objects wound with floccules can be pressed at the bottom of the sieve tray by the large materials to block sieve holes, and the small metal objects wound with floccules are difficult to output and difficult to collect due to the fact that the weight is light and cannot move to the surface of the materials from the bottom of the sieve tray through vibration, and the sorting efficiency is affected. Meanwhile, the existing material screening device only sorts materials meeting the specification requirement through vibration, and materials which do not meet the specification cannot be collected rapidly through vibration, so that the automation degree of the sorting process is low. Disclosure of Invention In order to solve the above problems, the present utility model aims to provide a push-pull vibration sorting device, which can enable small materials which are light in weight and cannot pass through sieve holes to be exposed above the materials and rapidly move to a discharge hole of a sieve tray, so as to improve sorting efficiency and material analysis accuracy.
